United States Patent BRUSH AND BRUSH HOLDER COMBINATION William J.Brady, Fairlawn, N. J. Application November 10, 1953, Serial No. 391,277

2 Claims. (Cl. 15--184) This invention relates to brush and brush holdercombinations, with particular reference to water color brushes, and is acontinuation in part of the instant inventors pending application SerialNo. 384,469, filed October 6, 1953.

The main object of the present invention is the provision of certainnovel and useful improvements serving to protect the brush when notbeing used and thereby prolonging the useful life of the brush, aswellas permitting of easy and quick change of the brush from a positionof concealment and protection within the holder to a position ofprojection of the brush from the holder ready for use.

A further object of the invention is a novel brush and brush-holdercombination adapted to have a single brush concealed and protectedtherein or to have two identical or similar brushes associated therewithand adapted to be singly or both simultaneously either concealed andprotected within the holder or to be singly or simultaneously positionedprojecting from one or both ends, respectively, of the holder, so thatthe single holder will contain a separate brush at either end wheneverdesired. The utility of the latter provision is readily apparent,especially in case each of the two brushes is to be used for applying adifferent color of paint.

The above as well as additional objects will be clarified in thefollowing description, wherein characters of reference refer tolike-numbered parts in the accompanying drawing. It is to be noted thatthe drawing is intended solely for the purpose of illustration and thatit is therefore neither desired nor intended to limit the inventionnecessarily to any or all of the exact details of construction shown ordescribed except insofar as they may be deemed essential to theinvention.

Referring briefly to the drawing, Fig. l is an elevational view of abrush and brush-holder combination embodying the principles of thepresent invention, with the detachable brush concealed in the holder,and further illustrating in phantom how the brush is withdrawn from theholder.

Fig. 2 is a similar elevational view of the device, but illustrating howthe brush is inserted into the holder ready for use.

Fig. 3 is a view showing the combination with the brush positioned readyfor use.

Fig. 4 is a sectional view taken on the line 44 of Fig. 1, showing alsoin phantom the brush ready to be dropped into the holder into theposition thereof shown at the bottom in full lines and also shown inFig. 1.

Fig. 5 is a fragmentary exploded perspective view, with parts brokenaway and partly in section, of one of the two identical ends of theholder barrel and the associated end sleeve.

Fig. 6 is an elevational view, with parts broken away and partly insection, of a modified form of holder barrel provided with two identicalbrushes, one of which is adapted to be positioned projecting from eachend for use as a double brush.

2,803,029 Patented Aug. 20, 1957 Fig. 7 is an elevational view of thelower half of the device shown in Fig. 6, illustrating the manner ofremoving the lower brush from the lower half of the barrel.

Fig. 8 is a view similar to Fig. 7 but illustrating the manner ofinserting the brush into the lower half of the barrel for concealmentand protection therein.

Fig. 9 is an elevational view of the modified device shown in Fig. 6,showing both brushes concealed within the barrel.

Referring in detail to the drawing, Figs. 1 through 5 shows the devicein one form, that is, wherein the barrel 10 comprises a hollow ortubular member having any desired external configuration, but beingformed of one pieceand having an axial passage 11 therethrough, ofconstant diameter. At each end the barrel 10 has a threaded flange 12 ofreduced external diameter, and projecting therefrom are a plurality ofelongated circumferentially spaced resilient prongs 13. The internaldiameter of the imaginary cylinder in which the prongs 13 lie, isnormally equal to the diameter of the passage 11. Two identical sleeves14 are provided, one for each end of the barrel. Each sleeve has aninternally threaded flange 15 whereby the sleeve is adapted to bethreaded on the barrel flange 12, and a tapering or conical body 16whose internal diameter diminishes from the flange 15 to the openextremity 17 of the sleeve.

In association with the barrel 10 is the brush 18, the latter comprisinga cylindrical stem 19 whose diameter is smaller than that of both thepassage 11 and the open end 17 of the sleeve 14, and the brush bristles20.

It is apparent from the above that when a sleeve 14 is screwed down upona barrel flange 12, the prongs 13 of the latter are brought together, sothat when the stem 19 is positioned as shown in Figs. 1 and 4, either atthe top or bottom end of the holder, it will be securely held inposition.

Assuming that the device is in the condition shown in Fig. 1, that is,unready for use as when in storage, and it is desired to prepare it foruse, the bottom sleeve is unscrewed a sufflcient distance to permit theprongs 13 to release the stem 19 to permit the brush 18 to fall throughthe bottom of the sleeve. With the sleeve 14 still partly unscrewed, asshown in Fig. 2, the brush 18 is turned upside down and the stem 19 isreinserted into the sleeve. When the brush has been properly positionedfor use, the sleeve 14 is screwed tight on the barrel, as shown in Fig.3, so that the prongs 13 will press against the stem 19 to hold thebrush securely.

To restore the brush within the barrel, as shown in Fig. 1, the deviceof Fig. 3 is turned upside down, the

then top sleeve 14 is unscrewed sufflciently to loosen the stem 19 topermit the brush to fall down the passage 11, and then the lower sleeve14 is unscrewed to permit the stem to assume the position thereof shownat the bottom of Fig. 4. Both sleeves 14 are then tightened.

In the modified form shown in Figs. 6 through 9, the only structuralmodification consists in the provision of the barrel 10a in twocomplementary halves or parts 21 and 22, the former having an internallythreaded flange 23 in which an externally threaded flange 24 on thelatter engages to unite the halves into a single barrel 10a. This barrelis adapted to carry two brushes, one at each end when both are to beused, or one only at one end and the other concealed when but one brushis to be used, or both concealed when the device is not in use. Themanner of manipulating the two brushes 18 is illustrated in thesefigures, and is believed unnecessary to be described in detail, exceptto state that each brush 18 remains always associated with the samehalf-barrel 21 or 22, the stem 19 in every case being released orsecured exactly as above described, that is, by unscrewing or screwingdown the corresponding sleeve 14.

Obviously, modifications in form or structure may be made Withoutdeparting from the spirit or scope of the invention.

I claim:

1. A device of the class described comprising anelongated barrel havingan axial passage therethrou'gh of constant diameter, said barrel havingan externally threaded flange at each end thereof, two identical endsleeves each comprising a conical body having a conical axial passagetherethrough and having an internally threaded flange on that endthereof having the largest diameter, each of said sleeves being screwedon one of said barrel flanges by threadable engagement of the sleeveflange with the barrel flange, each of said barrel flanges having aplurality of elongated circumferentially spaced resilient prongsprojecting therefrom into the adjacent of said sleeves, said prongs oneach endof the barrel when unfiexed lying in an imaginary cylinderhaving the same in: ternal diameter as said passage, said prongs beingflexed toward the center of said cylinder upon tightening of thecorresponding of said sleeves on the barrel, and a brush comprising acylindrical stem having a diameter smaller than the diameter of saidpassage and smaller than the smallest diameter of the sleeve but largerthan the smallest diameter of said prongs when flexed as aforesaid, saidbrushincluding brush bristles extending longitudinally from one endthereof, said brush being loosely and freely slidable through saidpassage in both directions, said stem being adapted to be positioned ineither end of the device and secured therein with the bristlesprojecting therefrom or in reverse position, said brush in either ofsaid positions being secured by tightening of the sleeve on the barreland thereby clamping said prongs against said stem.

2. The device set forth in claim 1, said barrel being divided midway ofits length into two equal half-sections having said axial passagecontinuous therethrough, said half-sections having means for releasablyinterlocking the same together in alignment, and an additional brush andlikewise freely slidable through said axial passage identical withsaidfirst-named brush, said first-named brush being associated with oneof said half-sections and said additional brush being associated withthe other of said half-sections.
